CVE-2026-74259

A flaw was found in the Linux kernel's Common Internet File System CIFS implementation. A local user could trigger a null pointer dereference by unmounting a CIFS share while certain files are still being processed. This could lead to a system crash, resulting in a denial of service...

CVE-2026-72315

A flaw was found in the Linux kernel's SMB client cifs. This issue occurs due to a delayed release of dentry reference counts during direct I/O DIO operations. When a file system is unmounted while these operations are still pending, it can lead to a "busy dentry" warning. This prevents the...

kernel: fs/smb/client: fix out-of-bounds read in cifs_sanitize_prepath

A flaw was found in the Linux kernel's CIFS Common Internet File System client. When the cifssanitizeprepath function processes specially crafted input, such as an empty string or a string containing only delimiters, it can attempt to read data beyond its allocated memory buffer. This out-of-boun...

CVE-2026-72318

A flaw was found in the Linux kernel's CIFS component. A remote attacker could exploit this vulnerability by providing a specially crafted Distributed File System DFS referral. The system fails to properly validate string offsets within these referrals, which can lead to an out-of-bounds read. Th...
